It is an essential part of software development to handle errors correctly and iOS development is no different. It is important to reduce the impact of the error to your user and inform your user clearly if an action is required.
Here is the extension that you will need to add to your project and the implementation of how you would present the UIAlertController within a UIViewController class.

iOS share sheets are a great way to allow your users to share content from your app. This is a great way to provide your users with the ability to share your app with their network of friends and family for you. A recommendation from somebody you trust is both more powerful than an advertisement and free for the app owner. It is also very easy to do.
Firstly, add this extension to the UIViewController to your project. It requires you to pass in your object and will present a share sheet for this object on the active UIViewController.

Next, we have the implementation, we want to create an object with three parameters (text, image, and url), then we call our presentShareSheet function from our extension.

As you can see we are doing this inside an IBAction, so we can create the share sheet whenever we like. And something like the image below is what you should see.
The full source code for a test project I have created for displaying iOS share sheets is available:
